Doesn’t register number. Really poor design
Further update to below I have been told by Zamtel that this app is simply not compatible with iOS, which explains a lot. Simply put this doesn’t work. When registering your number the keypad covers the text box so you can’t see or edit your input. You then get a series on registration codes by SMS. (For some reason 3 each time). Then you wait and eventually you get a Network Connection Error. That’s it. No where to progress from there. I’ll try again later but this app has clearly been designed by someone better suited to crushing rocks.
